GPU Profiling - Scenes

Can someone explain why the scene is listed twice and the cause(s) and implications of this.

I would like to know the answer as well.

I know it’s late to answer this, but for future reference:
It’s because you have multiple cameras rendering, maybe you opened the GPU_Visualizer inside the editor and you have a camera spawned inside the level (maybe that of the player pawn) so you have 2 cameras (editor+pawn) so to say that the editor preview of the level counts as well.

Nope. I have two scenes in gpu visualizer in an empty new level

yep, same here
